Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system for preventing illegal passage (backtracking) of automobiles traveling on toll passages such as highway passages.

Generally, high-speed passage interchanges are as shown in Figure 1 of the culvert.
One for up lane and one for down lane! Since tollgate 3 for I2 is on the same line, the cars that entered the expressway at the A and B (Z) interchanges exchanged A bamboo tickets at 0 points and met each other at point A, as shown in the llkz diagram. If a car enters the bath at point B' and a car enters the bath at point B, and a car enters at point B and exits the bath at point A', it should be A to B' and 8.
~Even though I have to pay the toll for 1 person, B-
There are drivers who rely on friends to pay the tolls for 8' and A-A', and this is causing a big problem as they lose 1 yuan in income.

Recently, a method has been proposed for Kof'L in which the JI #i1 place and entry time of the pass ticket are VTMed, and the distance and time when exiting the bath are used to detect unauthorized passage, but this method is a reliable check for fraud. can't do it.

The reason for this will be explained with reference to FIG.

In Figure 3, A, A', B, and B' are interchanges with the same meaning as in Figure 2, C is the place where you want to exchange a pass, t is A-=C%, t is C- A'.

t is determined by the time required for B-C, t4 is determined by the time required for C-B', and tmm'1. and tmm'1.8 are the minimum and maximum time between AHA' and FM' for determining illegal traffic, respectively.
+1m and l1ll'maxtl are also determined by the minimum and maximum time between B and B' for determining illegal traffic.

Here, in order to determine that it is illegal traffic, 1, + 1. ~jAA'm1m~tmm'1. N and t, 4-t, 4t□/1. ~tmm'□It's 8 o'clock,
The time on the max side on the right side may vary depending on the driver's driving personality and the congestion of the aisle, and the most important thing is that it must be determined by taking into account breaks at service areas etc. on the way, so there is considerable variation. As a result, the decision must be made with a wide margin, and this cannot truly prevent illegal traffic.

The purpose of this book @ Ming is to detect vehicles illegally passing on expressways and other toll roads by recognizing and comparing the absolute thing called the vehicle number. Out.

The above-mentioned object of the present invention is to provide a real recognition device for detecting the car number of a car and a car number storage device for storing the car number on a pass ticket at the entrance of a toll gate on a toll road such as an expressway; On the other hand, at the exit of the tollgate, there is a vehicle number recognition device that recognizes the vehicle number, a toll ticket reader that reads the number stored in the ticket, and a vehicle number information from the vehicle number recognition device and the toll ticket reader. This is achieved by providing a vehicle number verification device for verifying vehicle number information, and by verifying the above-mentioned pass ticket to detect illegal passage.

An embodiment of the present invention will be described below with reference to FIGS. 4 and 5.

Figure 4 is a configuration diagram of the toll gate entrance, and 4 is the I for vehicle number detection.
A TV camera, 5 is an image processing device that converts the car number optically inputted by the ITV camera 4 into an electrical signal and memorizes it, and 6 is a car number magnetization device that magnetizes the car number onto a card. 7 is a ticket issuing machine, 8 is an entrance gate that opens and closes automatically, and 9 is a car.

In the above configuration, when the car 9 enters the toll gate entrance, the ITV camera 4 for car number detection takes a picture of the car number of the car 9 and transmits the electric signal to the image processing device 5. do.

The image processing device 5 first processes the electricity g! The image is A/D converted and stored in the memory section.

Next, it is determined whether the signal contains anything other than vehicle number information (dust, dirt, electrical noise, etc.) (this is called preprocessing), and then a specific vehicle number extraction process (called % image extraction) is performed. Then, the car number will be recognized.

This car number information is further transmitted to the car number magnetization device fillt6, the car number is magnetized on the pass ticket (magnetic card), and handed to the driver via the pass ticket issuing machine 7. At the same time, the entrance gate 8 is opened and the car 9 will enter the expressway.

Next, Fig. 5 is a configuration diagram of the tollgate exit section, and 10 and 11 are I'I'' for vehicle number detection similar to the tollgate population section in Fig. 4.
V camera and image processing device, 12μ number reader, 13 a car number verification machine, 141 an alarm that alerts the driver when the vehicle inspection does not match, 15 an automatic hot water gate that opens and closes, and 16 a car.

In the above configuration, when the car 16 comes to the toll gate exit,
When the driver inserts the pass into the pass ticket reader 12, the reader 12 reads the car number t magnetized on the pass and sends the information to the car number collation machine 13. On the other hand, similarly to the tollgate entrance, the IT'V camera 10 for detecting the vehicle number captures the vehicle number of the vehicle 16, and the electric signal t-11iii
f# is transmitted to the processing iron 11. The ll1lif torture device 11 performs pre-treatment, IVi
The mold is extracted, the car number is recognized, and the information is sent to the car number verification machine 13.
Sent to. Here, the vehicle number collation machine 13 collates the vehicle number information sent from the above-mentioned pass ticket reader 12, and if they match, the hot water gate 15 is opened to indicate normal passage, and the vehicle 16 exits the expressway. Make it possible to pass. If there is a discrepancy between Teru and Yume, it can be considered as illegal passage (the ticket was exchanged somewhere), so the alarm 14 will alert you to illegal passage, and the hot water gate 15 will remain closed. After making the customer pay a prescribed fee such as an extra fee, the hot water gate 15 is opened to allow a car 16 to pass through. FIG. 6 shows an overall block diagram of the explanation of FIGS. 4 and 5.

As is clear from the above explanation, by handling information such as the car number, which cannot exist in multiple numbers, it is possible to reliably prevent illegal passage, and by adding an automatic toll collection machine to this embodiment, it is possible to prevent toll plazas. It is also possible to make it unmanned.

According to the present invention, since illegal traffic can be reliably detected, it is possible to eliminate the loss of revenue due to illegal traffic, which is said to amount to several billion yen annually just in the case of expressways.
